Hello,

For soldering copper pipe/tubing in the 1/2" to 1" range, what is the
proper size gap between the ID of the fitting and the OD of the
pipe/tubing? For example, the ID of 3/4" type L pipe is 0.785", while
the OD of 3/4" type L tube is 0.750"; would this be an acceptable
solder joint, or is 0.035" too big?

Thanks, Wayne


Ah. I think you have confused copper pipe and tube used for
general plumbing apps with the "refrigeration tubing" used
on things like A/C systems. In the latter case, tubing is
always speced by the tube O.D. And there are special fittings
designed to accept those dimensions.
